ABSTRACT:
A fluorescence spectrophotometer in which a monochromatic beam of radiation is directed from an excitation monochromator through a first optical system to a sample being evaluated. Fluorescence from the sample is collected by a second optical system and is directed to an emission monochromator. These optical systems are arranged such that slit images from the respective monochromators lie in a single plane defined by the intersecting axial rays of the excitation and fluorescence beams. In several advantageous arrangements the optical system includes aspherical mirrors arranged to give different magnifications of the images in the horizontal and vertical planes. The intensity of the excitation beam applied to the sample and of the output signal may be further increased by positioning wedge shaped optical elements adjacent the sample.
